WILLIAM BERND LEWIS W. BURDEN, OF NEW RICHMOND, VlTISCONSl' ADJUSTMENTDEVICE FOR QUAQK-GRASS P'Lows;

To all whom it mag concern:

Be it known that we, WILLIAM BERND and LEWIS W. BURDEN, citizens of theUnited States of A nerica,'res1ding at New Richof Wisconsin,

county of St. Groix and State have invented certain new and AdjustmentDev'u zes of which the "followmond, in the useful Improvements in forQuack-Grass Plows,

ing isa specification.

, The present invention relates to agriculturalimplements and consistsin the combinationsand arrangements of parts hereinafter'dis closed andparticularly set forth in qthe accompanying claim. .1

"Theinvention-has for its purpose to provide an adjustment device forthe steering wheel of quack grass plows which may be ulated from thedrivers seat,

readily mani lbe easy and positive in operaand which. wi

tion'.

Other advantages of the invention will appear in the course of thefollowing specification, and the appended drawings'wherein:

Figure 1 is a top ment. Fig. 2 is a side elevational view of the same,and Fig. 3 is a front elevational 'view thereof.

Referring to the construction in detail and wherein the samereferencecharacters indicate corresponding parts in the different viewsshown, the implement comprises a frame constructed of longitudinal barsl,v 2 and 3 connected by the cross-bar 4 at the forward end anda similarcross-bar 5 adja cent the rear end. An axle 6 is suitably mounted on theframe and has journaled thereon ordinary tractor wheels 7 and 8. Asecondary frame is secured to the main frame at the front .endthereof bythe an ularly disposed bars 9 and 10 and consists o a pair of side bars11 and 12, having a connecting cross-bar 13 (see Fig. 1).

A plow standard 14'is adjustably mounted on the secondary frame by meansof a' pair of runners or stirrups 15 and 16 that are 'sw-ing'inglymounted in suitable bearings 17 and 18 on said frame and have similarengagement with the plow standard asindicated at 19 and 20 in Fig. 2.A'plow 21 is carried by the standard 14' after. the usual manner and isprovided with an ordinary mold board 22 that is disposed to deliver theunearthed material on to the sorter and conveyer as'will be presentlyexplained The means for adjusting the plow 21 for plan view of theimple.

working at different depths, or for carrying the same clearof theground; consist of a shaft 23 that is journaled in the frame bars 11 and12 and has pivot'aljconnection withthe plowstandard 1.4- by an arm 24and a link 25. A lever 26 is fixed on the shaft 23 andv carries atreadle 27 for engaging with the foot of the operator, who sits on theseat A hand actuated lever'29 is likewise fixed to the shaft 23 andcarries a pawl 30 for engaging with the rack 31 to hold the plow in setposition "as will be understood. The pawl 30 is disengaged by means ofthe hand release 32 after the ordinary manner.

' A bracket arm 33 is secured to the frame bar 12 and has a sleeve 34which receives a vertical shaft 35 that carries a caster or steeringwheel 36 at its lower end. The

frame is adjusted indifferent positions by means of a lever 38 fulcrumedon the bracket arm 39 and connected to the swiveled'collar 40'on theshaft 35 by a link 41. A rack 42 is mounted on the frame and is adaptedto be engaged by a pawl (not shown). carried by said leyer38 forsecuring the frame in its adjusted position, as with the lever 29. i

The draft is connected to the implement by a cross-bar 43.secured to'the clevis 44, through a the frame. The tongue 47 for the steerin wheel36 is hingedly connected to the sha 35 as shown at48. saidhinge' '48 iscarried by a collar. 48" secured on the shaft 35, and

the collar40 is swiveled on said collar 48 .whereby the tongue 47 .maybe operated without interfering with the adjusting mechanism. f.

An endless conveyer 49 is mounted on the link 45, and an end piece '46on vehicle toreceive the material from the mold board .22. Said conveyertravels on thelarge and small sprockets 50 and 51 and is driven by thepinion 52 from the pinion 53 onthe shaft 54.. The shaft 54 is in turnconnected to be driven from the. axle "6 by the chain and sprocket drive55,66 and 57..

A second conveyer 58 is mounted on the vehicle frame and travels onpinions 59 (one pair being shown), after the manner of the conveyer 49.Said conveyer 58 is located to receive the material from the conveyer 49and is driven from the shaft 54 through the miter gear 60, the shaft 61,and a'secgond miter gear 62 connected to the sprocket shaft 63; A seconddrive for theconveyer 58 consists of a bevel gear 64 meshing with.

I "A pair of agitators 55mm (iiSintegratOrs 5 is associated. with themain conveyer and.

consists each of a, drum or cage '65 having a plurality of spikes orfingers 66-that are dis- 7 posed to engage with "the: material beingconveyed by the belt 49 'nd-in' so doing: to beat up or agitate thesame. for. loosening (the earth adhering to the rootsof-grass that hasbeen excavatedby the plow; The twp zigita'tors o'r'disintegratorseredriven at any 'suitablej'speed,each"by;a' eliainjend sprocketgen-ring 67, from the driyingshatftfikof the main conveyeiv.

The driving sha'ftf54 maybe thrown into or out of operation by{'meansyof,the .Cllilh -"'ver-' fuicrumed on the arm .:of the bracket,
